SPECIFICATION forming part of Letters Patent No. 776,272, dated November29, 1904.

Application filed October 1'7, 1904. Serial No. 228,721. (No model.)

To all whom it may concern:

Be it known that I, JOHN T. TowsLnY, a citizen of the United States ofAmerica, and a resident of Cincinnati, county of Hamilton, State ofOhio, have invented certain new and useful Improvements in AdjustableStops for the Tables of Band-Saws, of which the following is aspecification.

The object of my invention is an attachment for the table of a band-sawby means of which the workman from the front of the table may readilycause the table to take a back tilt at the angle used in cutting certainclasses of work, the attachment automatically readjusting itself whenreleased from the inclined position to cause the table to rest in aperfectly horizontal position without the use of levels, plumbs, &e.

In the accompanying drawings, Figure 1 is a front elevation of aband-saw the table of which is provided with my adjustable stop, thedotted line showing the table inclined in a backward and in a forwardposition. Fig. 2 v is a detail View, upon an enlarged scale, partly infront elevation and partly in section, showing the position of the stopwhen the table is in a horizontal position. Fig. 8 is a view similar toView 2, but showing the table inclined backward. Fig. 4: is a similarView with the table inclined forward. Fig. 5 is a detail View, upon asomewhat more enlarged scale, taken from the left side of the table,showing the stop in the position it occupies when the table ishorizontal.

Referring to the parts, the frame A, pulleys a a, the band-saw B, thetable O, having a curved bracket 0 upon its under side to rest in acurved bearing a on the end of the frame, the clamping-bolt I) forlocking the bracket 0 in its bearings (0 and the eccentric crank d forengaging the bolt D are all of ordinary construction and need not bemore specifically described.

The table has a slot 0 extending rearward from its front end for thepassage of the saw B, the slot being beveled upon each side '0 c topermit the table to be tilted without affecting the saw. Upon its innerside table O has a recess 0", within which is seated the adjustablestop, which consists of a cam-shaped disk E, which is rotatablyjournaled upon journalpin 6, which is seated in the side of the table.Upon side 6 disk E has an internal screwthreaded recess to receive anadjustable screw 6 which has a locking-nut c to hold the screw in theposition to which it has been adjusted.

Upon its side at a short distance from the screw a disk E has a lug Theupper edge of the disk E is knurled and is made flush with the topsurface of the table.

In use after disk E is secured rotatably to the side of the table screw0 is adjusted so that when the disk E stands in its normal position,such as shown in full line, Fig. 5, it will causethe table to have aperfectly level position when the head of the screw rests upon thehorizontal arm a of the frame. desired to work with the table in thisposition, it is clamped there by means of the crank (Z and bolt D.Should it be desired to use the table to out a bevel on the work, suchas is used in bevel-patterns, the workman loosens the bolt 1) and withhis finger rotates the disk E and allows the lug e to rest on the armof, as shown in Fig. 3. The table is then at the desired inclination,since the lug c" is made of a length such that it causes the table totake the right angle for cutting the normal bevel. IN hen the clamp (Zand bolt 1) are loosened and the table tilted forward again, the disk Eautomatically assumes the normal position, because the disk is heavierupon the side in which the screw 6 is inserted. Recess 0" has upon itsside a projection 0 which contacts the lug a to cause the disk to assumea position such that the screw 0 rests flat upon its head on the arm aShould the table be tilted forward, as shown in Fig. 4, the disk E willcause the table to rest in a horizontal position when it is released.

It is seen that the operation of causing the table to take the desiredbackward tilt is extremely simple and may be performed by the operatorwithout his leaving the front of the table where he has been working andthat the resetting of the table to a horizontal po- If it be sitionafter having cut a bevel is obtained Without any adjustment or the useof any tools, such as levels, plumbs, &c.

What I claim is 1. The combination of a frame, a table mounted rotatablyin the frame, an oscillatory disk secured to the side of the table andadapted to be rotated to cause it to rest upon its side on the frame,and an adjustable screw upon another side of the disk to cause the tableto take a horizontal position when said screw contacts the frame.

2. The combination of a frame, a table mounted rotatably in the frame,an oscillator disk secured to the side of the table with an edgestanding flush with the surface of the table and adapted to be rotatedto cause it to rest upon its side upon the frame, and an adjustablescrew upon another side of the disk to cause the table to have ahorizontal position when said screw contacts the frame.

3. The combination of a frame, a table mounted rotatably in the frameand having a recess upon one side, an oscillatory disk secured withinthe recess and adapted to be rotated to cause it to rest upon its sideupon the frame and an adjustable screw upon another side of the disk tocause the table to have a horizontal position when said screw contactsthe frame.
